Thanks for the info. I was wondering how this would be tackled owing to the fact, as you say, that the ditch ended at a point that is now inland. For anyone interested but not aware of this, here is an overlay on top of the existing layout showing the original configuration.

There are plans and visualisations, but I'm not sure if they have been made public yet. From what I have seen the Barrier Ditch is likely to become publicly accessible. The rampart and guardhouse will be restored between Dock Road/Church Hill and the river, but the ditch will not be fully excavated. Instead the course of the ditch will be marked out in paving and the original line of the footbridge will be indicated. The line of the riverfront has changed by several meters since the ditch was filled in, so there will be an area of grass between the end of the indicated ditch and the river.

A 'fort' themed adventure playground will also be included, and it may be that part of the ditch is exposed to full depth, but with a glass floor over it at the reinstated ground level.

This will entail the demolition of the Riverside One building to expose the missing part of the Barrier ditch and will include "a new entrance to Fort Amherst from Chatham town centre". I can only assume this means via Barrier Road. The restoration of the Spur Battery is also included.

I was wondering if there are any plans or visualisations of this project as I haven't seen anything published.
